3x EoM Priest (divided neatly by about 20-30k each, slow moving you can down each one before they close in too much)

Blitz: you may kill left group of EoMs and kill each newcoming group without even touching mid and right groups. Once you kill cruiser, mission is done.
At the Demon + Succubus spawn, you only have to kill the trigger and leave the Succubus.
